Hello Georgie, welcome to this site. We have all been where you are before and not really knowing how to proceed. We all have a certain amount of fear when we start our transition because of the unknown. But we have all found that a lot of the fear is self inflicted.
The best thing to do is to take each step in the process as it comes up. The first step is going to be to get yourself an experienced gender therapist that can help guide you through the process. Most therapy occurs online due to Covid conditions and so that person could be anywhere. I also recommend getting into a local trans group and developing some local trans friends that are further along in their transition. They can definitely help you with knowing where the local resources are in your area.
And certainly getting in contact with some of the Transgender Heaven members that live in your area. Go to Social, Member Directory and search for your area.
Best wishes.
